Abstract
A display device including a base substrate, a pixel disposed on the base substrate, and a color filter part disposed between the base substrate and the pixel. The color filter part includes a color filter corresponding to the pixel and a black matrix disposed at at least a side of the color filter. The pixel includes a cover layer defining a tunnel-shaped cavity on the base substrate, an image display part disposed in the tunnel-shaped cavity, and first and second pixel electrodes and a common electrode applying an electric field to the image display part. The tunnel-shaped cavity is formed by forming a sacrificial layer and wet-etching the sacrificial layer.
